1976 US Penny with 2.8 gram?

I got it out from my very old coin collection book.
Yes, it is damaged but it is only 2.8 gram, 18.95mm and the coin showing vivid words under 1976 mint.
I researched and learned that few 2.8 gram penny were minted by mistake (1945 & 1955 wheat penny).
It looks like my 1976 penny was definitely struck over 2.8 gram used coin.
Can somebody guide me?
Thank you

    first a public service announcement: according to ebay lolololololol

    a steel wheat cent weighs about 2.7 grams, we can rule that out though

    try looking at the details on the coin and see what bad shape they are in. the coin has had some chemical reaction eat part of the coin away thus the weight loss

    it is just a severely damaged cent. value of 1 cent

    if it won't go through a coin counter a bank will give exchange it for you

    That "article" was written by an AI, with typical AI logic. And typical AI inaccuracy.

    There are of course other explanations for a coin being lightweight. The most common is probably "the coin was soaked in acid". This coin has clearly suffered from some kind of chemical attack.

    Take a normal, 3.1 gram copper penny, and dunk it in Coca-Cola. Leave it there long enough, and you will end up with a coin that looks very much like this one, and weighing about 2.8 grams. It will also be slightly smaller and noticeably thinner than a normal cent.

    "But I can still see lots of detail ont he coin, wouldn't acid have corroded the detail away?" No. For a bronze coin, acid attacks all surfaces evenly, "preserving" the details even as the coin dissolves.

    You're wasting your time looking for error coins.

    It's an acid coin. Soaked in acid that slowly was dissolving it accounting for the light weight. Not any kind of error.

    Agree with all the above (except the OP).

    The thinning letters is a sign of acid damage.
    Just a PMD cent now.

    eBay A.I. wouldn't be my first choice for research.
